A Kiss to (Not) Remember for Alyssa Milano and Nathan Fillion on 'Castle'

Today's cuppa: English breakfast tea at the hotel, during the biannual Television Critics Association Press Tour

On Monday night, Jan. 11, former
"Charmed" star
Alyssa Milano appears in
"A Rose for Everafter," a new episode of ABC's hit mystery-drama
"Castle." She plays Kyra, a bride-to-be who is first shocked when a bridesmaid dies during her wedding, and shocked again when one of investigators turns out to be her old flame, mystery writer Richard Castle (Nathan Fillion), who arrives with his police partner, NYPD Detective Kate Beckett (Stana Katic).

"The storyline is that they were college loves," says Milano.
"Castle, in the episode, says I was the one that got away. It's really an unresolved relationship. They still have feelings for each other."

Evidence of that is the big smooch the two share, as seen in the photo at right.

Asked how it went, Milano says,
"Literally, of course, because this always happens, it was the first day of work, so it was a lot more awkward and uncomfortable than if it had been the tenth day of work, when I had known everybody. But it was fine. I don't really remember that much about it.

"Don't tell Nathan. He'll be so upset."

ABC has also picked up
"Romantically Challenged," starring Milano. for midseason. Since the actress is a prolific contributor to
Twitter, she will now have to balance a full-time job with her social-media interests.

"I make time for Twitter, no matter what," she says.
"It's such a part of who I am now. The only time I'm not tweeting is when I'm sleeping or on a plane or don't have Internet access."

She's already been using Twitter to promote her "Castle" appearance, as
has Fillion.
"I've been tweeting about it since I started. Nathan and I both tweeted a lot from the set together. He loves it. It lives us such a great platform to get information out there, not just self-promotion information, but cool information about things that are going on in the world.

"Everyone's really excited about the episode."

As fans of "Castle" may surmise, Beckett isn't overly fond of Kyra.
"Although she would never, ever show it," Milano says,
"there is definitely some jealousy there. But the Beckett character's way too stoic to actually show Kyra, my character, that she's jealous, but you definitely get the vibe that she may be upset about that."
